Support using more than one memory region
Opened this issue · 2 comments
The ESP32 (using esp-hal) has two memory regions that are usable, in the linker scripts as dram_seg and dram2_seg. Currently, this dram2_seg is unusable unless a user is to setup multiple heaps which is annoying to use. Can support be added to allow one Heap to both (or even more) regions of memory?
This was requested a few times, e.g: #40 and #16 . So I would be happy to merge a PR for this!
The implementation should not be too difficult. I think the deallocate function might even work for this, even though this behavior is not guaranteed. So adding a extend_with_region method should not be too difficult.
@GnomedDev I saw this the other day whilst thinking about another unrelated feature I wanted, and I thought I had an easy architecture to support this. I put it in the PR #84 if you want to test it. I've tested it on Nintendo Switch / Aarch64 and it works fine in my toy MVP app.
